In this report we offer a quick overview of each of the screens for mobile devices techniques so we can always know the difference between them, and we will discuss all of the AMOLED and Super AMOLED and LCD and IPS and IPS-LCD.
AMOLED screens

Alomoled began using AMOLED technology in electronic devices from mobile phones, digital cameras and media players, as of the year 2012, and continued development of this technology for progress towards production technique economize on energy consumption and production cost and large sizes.

Alomoled screen consists of a physical structure with bilateral symmetric bright LED screen or what is known as OLED, technology and active matrix organic light-generating, while Alomoled screen consists of material in terms of three layers: the screen and touch sensors and glass.

The AMOLED screen offers Alomoled sophisticated version of OLED technology, as it depends on organic compounds that emit light when exposed to an electric current technology, this process would reduce the need for a backlight and therefore less energy consumption.

Excel Alomoled screen on the TFT display in terms of the clarity of colors, and the speed of response, and the consumption of less of the battery, in addition to other features, the advantage that it does not use a backlight, unlike LCD displays, thus we get the dispersion less in light of, the thickness of less (thinner), and when extinguished pixels give us a real black color, the colors more saturated.

It AMOLED screen problems Alomoled it difficult to read in sunlight, and is characterized by the colors Each pixel in this type of display is illuminated to produce himself, but to a lesser or stronger depending on the color supply.
Super AMOLED screens

The Samsung Alomoled using technology with integrated digital converter, and this means that the layer that senses touch has been integrated in the screen. According to Samsung, the Super AMOLED technology reflects the amount of sunlight fifth compared with the first generation of Alomoled any that did not change the display technology itself, Super AMOLED is part of a family matrix Pentile, sometimes known as SAMOLED and abbreviated.

Feature Super AMOLED screen Super AMOLED sensitivity to touch better, with the integration of touch sensors in the screen itself and became only consists of two layers, a screen with sensors as well as the top of the glass, and this makes the screen more sensitive to touch.

It is also characterized by super AMOLED screen Super AMOLED more clearly under the sun, where she was one of the problems of screens Alomoled it difficult to read under the sun, compared with TFT screens, but in the Super AMOLED This problem has been resolved.

It also provides an improved viewing angle, where the colors do not change when you consider the oblique angle of the screen instead of direct view, where the loss is in the color when you tilt the screen almost non-existent, this feature already exists in Alomoled, but has been improved in the Super AMOLED.

Super AMOLED screens is also characterized as being thinner, due to reduce the layers, integrating the touch layer in the screen directly, as they offer the best colors, as the colors up to the eye directly without a layer touching the screen, and the color black appears blacker and white whiter , and the contrast ratio has a good effect on the degree of purity of the image.

But the biggest flaw in these screens as a few brightness screens, and that was a major cause of poor performance of the content of this screen under sunlight, the other point is the high cost of production, which is not a problem because Samsung manufactures screens themselves.

This and the Korean company Samsung Alomoled improving every year in the new phones screens by putting it under Diplay Mate and Anandtech tests, Fshahat own Super AMOLED Samsung company has become more accurate and provide more natural colors have been especially improve the efficiency of energy use.
LCD displays

It is the abbreviation of the term scientific Liquid Crystal Display, a technique used for some time in many television screens, computer and a number of other devices compared Alomoled panel which has a lot of support now.

Edit your LCD screens are made of two layers of glass and light passes through the liquid crystals liquid crystals, is the main feature of these screens are the colors, where this technique helps to show the colors naturally and is one of the best techniques in this area.

This screen lacks contrast ratio in Alomoled screens, there is a term linked to another edit your screen LCD, a TFT or Thin Film Transistor, in addition to some improvements on this screen and you give some preference in terms of quality.
IPS screens

Beginning IPS symbolize the in-plane switching has IPS screens are designed to improve the TN technical defects, were invented IPS technology in 1996 by Hitachi, where the goal was to first improve LCD screens, which were based on TFT technology, which were not according to the requirements and necessary quality.

It was taking longer response time, particularly in regards to viewing angles and color gradients, but that this was not an obstacle in computer monitors, unlike smart phones and tablet screens, Fshahat IPS provides whiter bright colors and bright and viewing angles are better than TFT technology.

IPS now have great contrast and good black levels, however response times still do not compare with the standard TN, negative thing in this technique is the backgrounds of large energy consumption.
IPS-LCD screens

It is a kind of thin screen that offers better viewing angles of TFT-LCD screens, featuring LCD IPS screens used it Tranzstoran per pixel while using the TFT-LCD screens only one.

And this requires a more powerful lighting, which provides more accurate color and clarity, and allows a wider angle of vision, and greater clarity and accuracy, while the negative side in the IPS LCD screen it may consume more of TFT-LCD capacity.
